Electronic Screening Brief Intervention (e-SBI) has been shown to be an effective prevention tool, and it has been implemented on personal computers, web, mobile phones and social networking platforms. In this research, we asked college students to discuss about their perception of BACtrack Mobile Pro, the FDA-approved and consumer-oriented smart breathalyzer. We recruited 15 college students who have consumed alcohol regularly, asked them to use the smart breathalyzer for two weeks, and conducted pre-and post-study surveys and interviews. We identified five barriers with design opportunities for the smart breathalyzer: (1) Support from immediate family members or close friends, (2) Personalized results, (3) Intuitive status display, (4) Ac-cessorizing the form factor, and (5) Quicker access. Future mobile and smart wearable e-SBI interventions targeted at college students should take these design considerations into account.

Research has explored the factors influencing male and female participation in competitive games, but little has focused on analysing gendered character choice and playing style preferences based on large in-game dataset. This research utilizes a mix-methods approach to examine gender differences in one of the most popular multiplayer online battle arena (MOBA) games, League of Legends (LoL). The results show that gender stereotypes affect the in-game character design, players' perception of abilities, and social convention in LoL, which further caused the gender differences of in-game character choice and playing style. We discuss design implications to make LoL more inclusive to female players.

Few technologies has been utilized to promote the therapy in terms of its system and influences on clients and other stakeholders. We are conducting a study aiming to (1) understand stakeholders and their current practices and issues of the therapy which involve several stakeholders; (2) explore what and how technologies could support the stakeholders; (3) to design and develop technologies to promote equine-assisted therapy for the stakeholders. Observations and interviews have been conducted at a local facility for equine-assisted therapy, and we bring up additional questions considering other subjects (clients and horses) who need to be noticed differently.

Anxiety is one of the most common and debilitating co-occurring conditions in adults with autism spectrum diagnoses (ASD) and there are few, effective treatment options for this symptom. Research is needed to explore the potential of using PA participation as an adjunct treatment to alleviate anxiety in adults with ASD.
Objectives: The objective of this pilot study was to examine the relationship between PA, sedentary time, and anxiety in adults with ASD using a modified ecological momentary assessment.
Methods: Fourteen adults with ASD and anxiety (10 females; mean age = 28.9, SD = 8.5) were recruited via ASD support groups in social media. A Qulatrics self-report survey addressing PA (modified International Physical Activity Questionnaire), sedentary time, and anxiety occurrence and triggers (Ozsivadjian, Knott, & Magiati 2012) was delivered daily via text message to study participants at 8 pm for seven days. Participants with at least 3 days of valid responses were included in the analyses. Descriptive and correlational analyses were performed using SPSS and significance level was set at p < 0.05.
Results: 65 responses were included in the analyses. Median moderate to vigorous PA and sedentary times were 15 min/day (IQR = 52.5) and 540 min/day (IQR = 420), respectively. The most frequently reported anxiety triggers were specific fears and phobias (46.2%), confusion and worries about social and communication situations (41.5%), and too many demands or expectations (26.2%). Also, participants experienced frequent anxiety feelings during 3 – 5 pm (50.8%), 11 am – 1 pm (40%), and 1 – 3 pm (38.5%). Moderate to strong correlations were found between sedentary time and anxiety (rs = 0.34, p = 0.005) and between moderate to vigorous PA and physical health satisfaction (rs = 0.61, p = 0.027). Moderate to vigorous PA and sedentary time were also moderately negatively correlated (r = -0.42, p = 0.001).
Conclusions: Adults with ASD show low levels of daily PA and are highly sedentary. High levels of sedentary time are associated with anxiety in adults with ASD. Interventions that target reducing sedentary time, rather than PA, as a way to manage anxiety in adults with ASD warrant further study.

They have experienced challenges such as quality of health care, care coordination, and risks of sudden unexpected death. People with epilepsy and their caregivers (PWEC) desire for more resources and improvement in self-management. Our goal is to develop a patient-centered web service for them. Before we develop it, we conducted a focus group study to understand their needs, concerns, contexts of health information management, and experiences. Our preliminary findings include: (1) information seeking for treatment and side effect, (2) information sharing challenges with families and caregivers, and (3) preference for personalization and tailored information. CCS CONCEPTS • Applied computing → Health care information systems; Health informatics; • Human-centered computing → Human computer interaction (HCI). INTRODUCTION Epilepsy is a chronic medical condition, which is one of the most common neurological diseases such as migraine, stroke, and Alzheimer's disease [3]. Over two million people in the U.S. are living with epilepsy [2]. Challenges of people with epilepsy include quality of care, care coordination, side effects, stigma, uncertainties of social situations, risks of sudden unexpected death, etc [1, 5]. PWEC desire to find more resources and services and improve their self-management [7]. Our research goal is to develop a patient-centered web service for PWEC which will improve PWEC's activation-the degree to which a person has the knowledge, skills, and confidence to manage epilepsy. Our research team will develop a personalized Automated User Resource Atheneum (myAURA) by integrating big data resources into a large-scale epilepsy knowledge graph that will fuel novel network inference methods to recommend and visualize relevant information in a personalized manner. However, before we develop the system, we conducted the first stage of our user study to understand PWEC's needs, concerns, contexts, and experiences in terms of health information management. We present preliminary results of this user study here.

These family caregivers can sometimes feel overburdened when juggling their caregiving responsibilities with the rest of their lives, and that can negatively impact their health. Respite care provides a temporary break to family caregivers. Even though there are benefits of using respite care, barriers such as uncertainty and mistrust exist. Our research is focusing on what trust issues caregivers experience and how information sharing through ICT could mitigate the issues and improve the quality of temporary care work. In this position paper, we present a summary of current issues and practices of family caregivers of older adults and respite care, and introduce our ongoing study to find ways to build trust through information sharing between family caregivers and respite care providers.

Electronic Screening Brief Intervention (e-SBI) has been shown to be an effective prevention device, and it has been instrumented on personal computer, web, mobile phones or social networking platforms. In this research, we asked college students to discuss about their perception of BACtrack Mobile Pro, the first FDA-approved personal smart breathalyzer. We recruited 15 college students who have consumed alcohol regularly and asked them to use the smart breathalyzer for two weeks. We conducted online surveys and in-person interviews. We identified five main issues of the smart breathalyzer from the participants: (1) Support from immediate family members or close friends, (2) Personalization, (3) Intuitive display of results, (4) Attachment to users, and (5) Quicker access. Future mobile and smart wearable e-SBI interventions targeted at college students should take these design considerations into account in order.

Sustainability, Jan 21, 2025

However, efforts to measure the social, environmental, and economic factors of sustainability are undermined by inconsistent understandings of the term. This research seeks to address this gap in sustainability research by constructing a wide-reaching propensity instrument that incorporates the different constructs of sustainability. A literature review informed propensity instrument construction. The first version of the instrument included 269 items, which were narrowed to 100 after an iterative process of merging, refinement, and elimination. The 100 scale items were deployed through an online survey, where 162 responses were collected to inform data analysis. Principal component analysis revealed two primary factors of Sustainable Behavior and Sustainability Attitude. After further refinement based on items' factor-loading scores and communalities, 13 items remained that described sustainability as environmentally and socially conscious behaviors and attitudes. The third construct of sustainability, economics, was not present after such refinements, suggesting that purely economic behaviors and attitudes are disparate from individuals' sustainability propensity. This new propensity instrument informs the understanding of sustainability and provides a tool for measuring sustainability with more breadth.

They experience difficulties in receiving proper care and support due to stigma and misconceptions. Promoting public awareness in early education would be critical to reduce the stigma and to properly support them. We conducted 145 surveys and 21 interviews with teachers, school nurses, and parents of elementary and middle school students. While the participants exhibited slightly positive attitudes towards PWEs, we identified obstacles that hinder learning about epilepsy and seizure first aid: inadequate education and limited information sharing among school stakeholders. Moreover, there is a pressing need for age-appropriate education that considers the students' ages and perceptual levels. Considering the current limitations and needs, we propose potential implications for future information and communication technologies (ICTs) designs, including knowledge-sharing systems and an educational game aimed at enhancing epilepsy awareness and fostering collaborative care in elementary and middle school environments. CCS Concepts: • Social and professional topics → K-12 education; People with disabilities; • Humancentered computing → Human computer interaction (HCI); • Information systems → Collaborative and social computing systems and tools; • Applied computing → Computer-assisted instruction; Health care information systems.

Public HIV-related stigma often leads to anxiety and depression and hinders access to social support and proper medical care. Technologies for HIV, however, have been mainly designed for treatment management and medication adherence rather than for helping people cope with public HIV-related stigma specifically. Drawing on empirical data obtained from semi-structured interviews and design activities with eight social workers and 29 people living with HIV, we unpack the ways in which needs for privacy and trust, intimacy, and social support create tensions around key coping strategies. Reflecting on these tensions, we present design implications and opportunities to empower people living with HIV to cope with public HIV-related stigma at the individual level.

Eighteen adults with and without ASD participated in a mixed-methods study that consisted of cognitive walkthrough, system usability assessment, and qualitative interviews. The results of the system usability testing indicated satisfactory quality of the PuzzleWalk system that can be readily applicable to both adults with and without ASD. Several notable issues were identified from the qualitative interviews that address critical insights into unique health and social needs in adults with ASD. Future work is warranted to examine the long-term effects of the PuzzleWalk system on increasing physical activity and reducing sedentary behavior in adults with and without ASD in real-world settings.

With 86 participants in total, we conducted surveys, interviews, and a two-week user study that involved the use of BACtrack Mobile Pro, an FDA-approved personal breathalyzer which can be connected to a smartphone app. For the user study, we conducted pre-study and weekly surveys, user experience evaluations, and in-depth post-study interviews with 24 college students who regularly consume alcohol. We identified and compared two groups of participants based on the Alcohol Use Disorders Identification Test (AUDIT), which is a screening test for risky drinking behaviors. We propose a new system, smartphone app user interface, and experience based on our findings. Finally, we discuss the role and implications of future technological interventions that could lead to safe and responsible drinking behaviors among college students.

Moreover, prior research has relied mostly on content analysis of forum posts at the post level. In order to generate a more fine-grained analysis of support exchange, we conducted content analysis at the utterance level, taking directness of support seeking, quality of provision, forum type, and seeker gender into account. Our analysis of four popular online support forums for people living with human immunodeficiency virus found that type of support sought and provided, support seeking strategy, and quality of emotional support provision differed in care provider/formal forums versus social/informal forums. Interestingly, indirect support seeking tended to elicit more supportive emotional responses than direct support seeking strategies in all forums; we account for this in terms of type of support sought. Practical implications for online support communities are discussed.

Objective assessment using activity monitors is needed to better understand physical activity (PA) and sedentary behavior in this population segment. The purpose of this study was to examine the general levels of PA and sedentary time in adults with ASD using accelerometry.
METHODS: Eleven adults aged 18-55 (6 females; mean = 31.9, SD = 12.5) and diagnosed with ASD were included in the study. Participants wore a GT3X+ accelerometer on their right hip for 7 days during waking hours except water-based activities, and accelerometers were programmed to collect data in 60-second epochs. ≥ 10 hours of device wear was defined as a valid day and ≥ 3 valid days was required for each participant to be included in the analyses. Activity intensities were determined using the following cutoffs (counts/min): sedentary <100, low 100-499, light 500-2019, moderate 2020-5999, and vigorous >5999 (Tudor-Locke et al., 2010), and non-wear period was determined by a minimum length of 90 min of consecutive 0-counts by Choi algorithm (Choi et al., 2011). Descriptive statistics were calculated for moderate to vigorous PA, light- and low-intensity PA, sedentary time, and walking steps.
RESULTS: The average total monitored length was 761.5 min/day (SD = 76.4). Results of the PA measures are as follows: moderate to vigorous PA - 42.8 min/day (SD = 30.5); light PA - 109.9 min/day (SD = 32.4); low PA - 97.9 min/day (SD = 33.9); and sedentary time - 511 min/day (SD = 84.6). The daily average percentage of time spent in moderate to vigorous PA was 5.8% (SD = 4.4), and the average step counts were 3799.7 steps/day (SD = 2953.9). 81.8% of the participants met the recommended PA guidelines of 150 min of moderate to vigorous PA per week.
CONCLUSION: Although the majority of adults with ASD in this study met the PA guidelines, they were also extremely sedentary. More research is needed to determine if sedentary time, rather than PA, should be targeted to improve preventive health in adults with ASD.
